Coulomb-bound four- and five-particle intervalley states in an atomically-thin semiconductor

Valleytronic devices of atomically thin transition metal dichalcogenides may benefit from high-order exciton complexes. Here, the authors present experimental evidence for four-particle biexcitons and five-particle exciton-trions in high-quality monolayer WSe2.
